To all whom t may concern:

Be it known that L STEPHEN HOFMANN, a citizen ofthe United States,residin at Brooklyn, in the county of Kings and tate of New York, haveinvented certain new and useful improvements in llVater-Faucet Washers;and l do declare the Jfollowing lto be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. Y

rllhis invention relates t0 improvements in valves for faucets and thelike.

rll`he principal object is to provide a valve adapted roruse in place ofthe ordinary valve to eliminate the grinding and cutting action whichthe seat has on the washer commonly used and in which the washer isrotated with the valve operating stem and valve with a double guide ierretaining it in its proper position.

Another object is to provide a simple and inexpensive valve which is-formed oi perA rnanently connected parts, one of which may be readilysubstituted for the ordinary valve by persons not experienced inplumbing.

With the above and other objects in view, the invention consists otcertainA novel features ot construction and the combination andarrangement of parts as will be more fully described and claimed.

ll attain these objects by constructing the valve as illustrated in theaccompanying drawings; in which- Figure 1 is at side elevation ott afaucet with parts in section showing the valve seated;

Fig. 2 is a detail vertical section oi the valve in its raised or openposition;

Fig. 3 is a view similar to Fig. 2, but showing the valve seated; l

lig. d is a side elevation of 'the valve; and,

lFig. 5 is a top plan view thereof.

ln the drawings a faucet F is shown pro-- vided with the usual valveoperating steni S, the lower end ot which is provided with the usualthreaded recess or socketA in which the ordinary valve is usualisecured. 'llhe faucet is ,formed with a partition P in which an openingis provided, the wall of the open ing serving as a valve seat. rlheahove description is that ot an ordinary faucet and it is understoodthat my improved valve is not limited to use on any particular style orpattern of faucet.

rlhe valve comprises a central stein l which rises vertically from thecenter of the Hat upper face oi an elongated head 2, said head being/preferably slightly tapered downwardly to assist in centering the valvein its seat. rlhe head 2 and the stem l are preferably formed integrallyfrom a suitable metal.

Preferably though not necessarily the upper tace of the head is shapedto torni an annular shoulder around the base of the stem .l to provide asupport for a washer 3, said washer being formed of rubber, leather,fiber or any other suitable material and provided with a centralaperture through which the stem is passed.

For the purpose of retaining the washer in position, l provide a flatdisk l preierahly formed or metal and provided with a central opening toreceive the stern 1 of the vaflve.

The stem is preferably tapered upwardlyv from its .base andhwhen theparts are assembled, the flat disk l is forced upon the stem, engages iticrictionally and clamps the wascllier tightly vagainst the ilat faceoit said hea *When a valve et this construction is to be substituted fora worn out valve, -the valvel operating stern is removed and the newvalve placed upon the seat with its head 2 entendv ing downwardlythrough the valve opening and serving as a guide for the valve when itis' seating itself. |lhere is no adapting or fitting to the seatnecessary in this valve, as the device is ready to he dropped to itsseat and to operate without further attention. Also, due to the tactthat the parte oit the valve are permanently secured together`` aunitary article will be had. Consequentlya the parts will never getlost.

rlhe water pressure will raise the valve when the operating sternisraised and when the stein is again screwed 'down the thrust et saidstein will be received on the dat disk l thereby eliminating grindingand cutting the washer.

rl`his particular torni or valve is absolutely certain to properly seatitself at all times., due to the double guide formed by the head 2 whichentends into the valve opening9 and evo .BREL

the stem 1 which projects and is loosely received in the recess orsocket in the lowerl end of the operating stem.

lt is well known' that in the ordinary type of valve, the screws workloose orbreak off afterV a short period of use and the disks arereleased and then the faucet is useless until repaired. Furthermore, ashereinbefore stated, rotation of the valve washer with the operatingstein quickly grinds and cuts away the washers and with a valve of theconstruction hereinbefore set forth these faults and others areeliminated. p

From the foregoing description, taken in .connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without re uiring a moreextendedlexplanation.

arious changes in the form, proportion and the minor details ofconstruction may be resorted. to without departing from the ieeaeoeprinciple or sacrificing any of the advanta es of the-claimed invention.
